The JDSU JSH-42L4DD1 SFP transceiver is a hot-pluggable, 3.3 V, duplex-LC transceiver designed for use in Fibre Channel applications up to 4.25 Gbps and in Gigabit Ethernet applications at 1.25 Gbps with rate select. The multi-rate feature enables it use in a wider range of system applications. It is compliant with FC-PI-2 400-SM-LC-M, 200-SM-LC-L,100-SM-LC-L, and 1000Base-LX specifications. The rate select pin (pin 7) along with the software rate select option provides optimized link performance between 4.25G/2.125G and 2.125G/1.25G/1.0625G line rates. These transceivers provide the LC optical receptacle that is compatible with the industry standard LC connector.

The transceiver consists of an optical subassembly housing the transmitter and receiver, and an electrical subassembly. All are packaged together with a top metal cover and bottom shield. The optical subassembly consists of two parts. The transmitter side has a high-performance, 1310 nm Fabry-Perot laser with back-facet monitor. The receiver side has an InGaAs PIN and a preamplifier.

The digital diagnostic monitoring (DDM) interface uses the same two-wire serial ID interface defined in the SFP MSA specification. The standard serial ID information is located at address A0h. Using address A2h, the user can monitor transceiver parameters, including temperature, voltage, laser bias current, laser power, and receiver power. Alarms and warnings are provided when the monitored parameters exceed predefined threshold values. All transceivers include a loss-of-signal- detect circuit, which provides a TTL logic high output when an unusable input optical signal level is detected.
